I use three-four tools to measure website performance: webpagetest.org for the individual pages, Rigor to understand the patterns and catch the problems over time, per location, Page Speed Insights and GA to measure the results. The head of our IT loves GTMetrix, which shows for some reason half number of the speed results compared to webpagetest, rigor and page speed insights which are all normally pretty consistent in generating objective reports. Why GTMetrix shows a lot better results and how to explain it to our infrastructure folks?
